You never know what you might find at any of the New England Antique Radio Club’s shows — there are telegraphs and transistor radios and everything in between.

The club’s 48th annual flea market-style antique show — aptly called “Radio XLVIII” — is happening Sunday, March 5, from 8 a.m. to 1 p.m. at the event center of the Nashua Radisson, making its first appearance in the Gate City. (Two other events are planned for June 3 and Oct. 21, both at the Brookline Event Center.)

With nearly 100 New England area and Northeast vendors appearing each year to sell old radios, record players, amplifiers and more, the event is known as the largest antique radio and vintage electronics show on the East Coast. For the past 15 years, the March shows were held at the Westford Regency Inn & Conference Center in Massachusetts, but the club decided to move them to Nashua in search of a larger space.

“We don’t define [our shows] as being just about old radios,” said Bruce Phillips, owner of Radio Orphanage and NEARC president. “It’s not really a computer show either, though, so calling it a vintage electronics show sort of separates it that way. … We’ll have people who will have record players, some televisions, some amplifiers and other things as well.”

Phillips said collectors from all over New England and other states like New York, Pennsylvania and New Jersey will be at the event to sell and buy from others, but their antiques will also be on display.

“[The vendors] will be at the show to sell and talk about their radios and other things, and people can learn about who deals in the area and who can repair them for you,” he said. “We’ve been trying to attract younger people who perhaps grew up remembering the old antiques their families had back in the 1980s and before then as well.”

The event is even an opportunity for a history lesson when it comes to electronics, for younger kids raised on more advanced levels of technology, Phillips added.

“I love seeing people coming in with their 8- or 9-year old, giving them a transistor radio or a rotary dial and showing them how it works,” he said. “The honest reality is that most of our vendors are between 65 and 80 years old and they are ready to move [the antique collecting] on to somebody else, so we like seeing younger vendors coming in and picking some of these up as well.”

From 8 to 11 a.m., admission is $10 for one person and free for children under 18 and spouses. During the last two hours of the event, everyone gets in for free. Several antiques and other prizes will be drawn from a raffle each hour, beginning at 9:30 a.m. Your raffle entry comes with your admission ticket if you pay to get in during the morning, but Phillips said additional raffle tickets will be available for purchase.

Onsite parking will be available for the duration of the show for free. In addition, Phillips said the hotel will be providing coffee and lunch items in the event center for a small fee.
